Whether you tend to max out your credit card on Cyber Monday, blast holiday music 24/7 or go hard on the Christmas cookie, everyone has something they overindulge in at the holidays.

For Holidazed star Rachelle Lefevre, she goes a little too big on holiday meal prep.

“I have a problem where I have so much anxiety about whether or not everybody’s going to have enough to eat,” Lefevre, 45, tells PEOPLE. “My husband’s a chef, he knows exactly how much food you need to buy for exactly how many people, and he tries to rein me in every year. I can’t shop properly. I just can’t do it. We have people over and then I look around at all the food and I’m like, ‘What did I do?’ And he’s like, ‘You did it again.’”

As a result, Lefevre always dreads “the guilt that I know is going to come with all the leftovers,” she says. “I have to beg everybody to take leftovers. So now when I go Chrismukkah shopping, Tupperware is on my grocery list because I know I’m going to send everybody home with food on the way out.”

The holiday chaos unfolds on-screen for Lefevre in Hallmark+’s first-ever holiday series Holidazed, in which she butts heads with her sister (Lindy Booth) when returning home for Hanukkah. Despite the tension between the Woods sisters following the death of their mom, Lefevre “was so excited” about a chance to pay homage to her Jewish culture.

“I’m Jewish and my mom’s Jewish. My bio dad wasn’t Jewish, so we do Chrismukkah at our house,” she says. “And I have sisters in real life, so not only did I get to do the sister dynamic, but then also we got to do Chrismukkah. It was a lot of fun, for me, bringing things in my life that I really cared about and actually had strong feelings about to our scenes.”

Lefevre also enjoyed working with Booth, 45. “In the first five minutes, I was like, ‘Oh, yeah. We could have been sisters,’” the Twilight alum says.

She remembers a warning Booth gave her when they first met.

“I remember when we realized very quickly that we were going to be friends for life, it was actually like, ‘We should get to know each other because we’re definitely going to be doing this for a lifetime,’” Lefevre says. “And at one point, she said to me, very seriously — it got really eye contact-y — she was like, ‘I have to tell you. I take Christmas very seriously.’ I was like, ‘I don’t know what that means.’ That was so oddly specific.”

Booth tells PEOPLE she thinks she and Lefevre were “possibly separated at birth.” “We did the DNA test,” Booth jokes.

She describes Woods sisters Lucy and Sylvie as “two sides of the same coin,” with the former being “very straight edged” and “by the books.”

“Her entire Christmas gets upended when Hurricane Sylvie shows up,” Booth says of her character Lucy Woods. “Her perfect life and her perfect world gets absolutely messy. And you see how this works.”
